IMPROVEMENT IN RAZORS. l

Specification forming part of Letters Patent No. 155,64, dated October6, 1874; application filed September 5, 1874.

To all whom t may concern Be it known that I, FERDINAND ERD- MANSKI, ofHiawatha, in the county of Brown and State of Kansas, have invented anew and Improved Razor, of which the following is a speciiication:

In the accompanying drawing, Figure l represents a side view of myimproved razor; Fig. 2, a top view of the razor-blade detached; Fig. 3,a sectional rear view of the razor; and Fig. '4, a vertical transversesection of the I same on the line c c, Fig. 3.

Similar letters of reference indicate corresponding parts.

The object of my invention is to produce an improved razorwithinterchangeable blades, by which not only time in honing is saved, butalso a considerable economy in the use of razors produced.

My invention consistsot a detachable blade, which is inserted into thesupporting back part or frame of the razor, being fastened therein byits hinged top half', which is secured by a suitable slide-piece orother locking device on the lower or main part. The steady position ofthe razor-blade is secured by means of pins of the main part of thesupportingframe, passing through symmetrically arranged holes of theblade into recesses of thc hinged part.

In the drawing, A represents a razor-handle of the usual construction,to which the main part B1 of the blade-supporting back part or frame Bis applied in the usual manner. The upper part B2 of frame B is hingedat the front end of the same, and fitted exactly to a recess of the mainpart. The top part B2 is be put in with the rear part to the front andwith the front to the rear, which admits of the use of the sharp rearpart after the front part has become dull, saving thereby time in honing. The top part of the blade C is provided with perforations a, whichfit on pins b ot' the main part Bl. The hinged part B2 has correspondingrecesses b for the pins, and is brought over the blade and pins so as tobind irmly thereon. The tongue-shaped end l of hinged top part B2 fitsinto a recess, d', of the main part B1, and is securely locked thereinby a dovetail slide-piece, e, passing laterally in a groove, e', acrossthe recessed end of thel tongue d.

Any other screw or equivalent fastening device may be used, as I do notconfine myself to the use of the slide-piece. One handle part andsupporting-frame may thus serve for any number of razor-blades which arereadily and conveniently inserted, so as to form a cheaper and moreeconomical razor for general use.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. As an improvement in razors, the combination ofsupporting back or frame B, consisting of main part B1 and hinged andfastened top part B2, with a detachable symmetrical razor-blade, C,substantially as and ,for the purpose set forth.

2. The razor-blade C, having pertorations a, in combination with pins botl the lower main part B2 and recesses b' of the top part ofsupporting-frame B, for the purpose of securing steady position ofblade, substantially as described.
